問題文
A retail client asks for a view that compares each store's sales with the average of all stores in its region, while the view itself shows one row per store. Which Tableau capability expresses that requirement most directly?
選択肢
- A parameter bound to the region, which lets the client switch the region shown in the view at any time.
- A level of detail expression fixed at the region, which returns the regional average next to each store row.
- A data source filter set on the region, which limits the rows to the stores of the region being reviewed.
- A dimension filter placed on the store, which narrows the view to the stores that the client wants to see.
